MILK STRAINER.

Application filed September 14, 1926. Serial No. 135,353.

The present invention relates to milk strainers and an object thereof isto provide a strainer which will support the strainer cl h or materialin such a manner that the of the same is prevented whereby cleaner milkis obtained. A further object of the invention is to hold the strainercloth or material effectively in position between two strainer elements.

To these and other ends, the invention consists of certain parts andcombinations of parts, all of which will be hereinafter described: thenovel features being pointed out in tie appended claims.

In. the drawings:

Fig. 1 is a vertical section through a str'iner constructed inaccordance with this in vent-ion i Fig. is a plan view;

Fig. 3 is a side view with the strainer cloth or material and theholding element removed F a i is a plan view of the holding cap;

5 is a side view of the holding cap;

6 is an enlarged section on the line 2 and an enlarged section on theline A strainer cloth or material for milk when supported only at itsedges sags at its center where it collects dirt which is eventuallyforced through the cloth or material by the pressure of the milk, thuscontaminating the milk. According to this invention, the cloth ormaterial is supported so that sagging at any point is prevented and atthe same time the cloth or material is clamped so that the dirt cannotpass beyond the edges of such cloth or material.

In the illustrated embodiment of the invention the strainer embodies afunnel member 1 which is formed from a single piece of stamping toprovide a reduced cylindrical portion having a strainer element 3 formedin one piece therewith and provided with a plurality of openings 4. Heldto this reduced portion 2 of the strainer element of the funnel memberis a strainer cloth or material 5. The holding means for this strainercloth or material is in the form of a cap 6 with a strainer element 7 inthe bottom thereof formed in one piece with the cap. About the strainerelement 7 is provided an imperforated annular rib 8 which is pressedfrom the cap inwardly to cooperate with an annular imperforated portion9 on the reduced portion 2 about the strainer element 3.

To hold the cap 6 to the reduced portion 2, any suitable means may beemployed. In this instance the reduced portion 2 has two diametricallyarranged pins or projections 10 which are adapted to enter into camslots 11 formed in the edge of the cap 6.

In arranging the strainer cloth or material in position, the strainercloth or material is stretched over the strainer element 3 of thereduced portion 2 and thereafter the cap 6 is fitted thereover, so thatthe pins or projections enter the cam slots 11, the turning of the cap 6after such entry efiecting the drawing of the annular rib 8 toward theimperforated annular portion 9 of the reduced portion and firmly bindingthe strainer cloth or material between the reduced portion and the cap.This forms a tight seal and prevents any of the milk passing upwardlybetween the cap and the reduced portion and confines the milk and thesediment to the strainer cloth or material. The strainer cloth ormaterial is held in a taut condition between the two strainer elements 3and 7 and cannot collect sediment at any one point. The openings in thetwo strainer elements will necessarily be out of alignment in mostinstances, so that the forming of pockets in the strainer cloth ormaterial is reduced to a minimum.

lVhat I claim as my invention and desire to secure by Letters Patent is:

1. A milk strainer comprising a funnel member having a cylindrical.portion provided with a bottom in one piece therewith, amulti-perforated central portion and an imperforated annular portionsurrounding the perforated portion, a cap having a cylindrical flangefitting the exterior of the cylindrical portion of the funnel member,said cap being provided with a bottom in one piece with the flangehaving a multi-perforated central portion, and an imperforated annularportion surrounding the perforated central portion, strainer materialarranged between the bottom of the cap and the bottom of the cylindricalportion of the funnel memher, and interlocking means between the cap andthe cylindrical portion of the funnel member having provision fordrawing the imperforated portion of the bottom of the cap against theimperforated portion of the bottom of the cylindrical member in order toclamp the strainer material. between the tWo bottom members.

2. A milk strainer conipdsing a funnel member having a cylindricalportion provided With a rigid bottom, said rigid bottom having aInulti-perforated central portion and an iniperforated annular portionsurrounding the perforated portion a cup having a cylindrical flangefitting the exterior oi the cylindrical portion or the tunnel nieinher,said cap being provided with a rigid bottom having a inulti-perforatedcentral portion, and an iinperforated annular portion pressed inwardlyto provide a rib surround ing the perforated central portion, strainermaterial arranged between the bottom of the cap and the bottom of thecylindrical portion of the funnel member, and interlocking niezinebetween the cap and the cylindrical portion of the tunnel. member havingprovision for drawing the rib oi the cap against the iniper'toratedportion of the bottom of the cylindrical portion in order to clamp thestrainer material between the two bottom portlone.
